Since I don't have a schematic for that radio to look at I'm not sure where
T3 is. Input to final transistors or output? Even so, direct comparison on
a wattmeter may be misleading. The impedance is different in various places
in the PA circuit, only the input and output to the whole PA board can be
assumed to be 50 Ohms. How about measuring voltage at those various points
using either a HF AC Voltmeter (the kind with the detector diode right
inside the probe) or an Oscilloscope with 10X probe?
